To all whom it may concern:

Be it known that I. ALFRED G. F. Konowa citizen ot the United States,residing in Brooklyn Borough, in the county of Kings, city and State ofNew York, have invented certain new and useful Improvements inTypewriting Machines, of 'which the following-is a specification.

This invention relates totypewriting machines, and moreparticularly totypewriting machines for typing bills :for telephone service. In the 7operation of typing these bills, it required to type separately theamounts of United States taxes. It is desirable the sainetiine to keeptrack of the total amount of the tax items for .a day or otherlongperio'd. This has been done heretofore by providing -a standardtypewriting machine withspecial 5 and 10 keys to be used tornootherpurpose than the writing of tax items, and by providing registers torsepar-atelycounting the operations of the special keys orxtor separatelyadding the items written by them.

A 'lieature of-the present invention is the provision, in a machinehaving special 5 and 10" keys tor-thapurpose mentioned, of asinglereg-ister and means for operating the register to cause it to addtogether the items written hyboth ot the specialkeys. This register is,in general, of thetype of the well-known Veeder cyclometer, but has itsunits wheel especially arranged to enable it to count by five.

The invention isnot limited in scope,.however, to use in a machineprovided with special keys for writingthe tax items, nor to keys forwriting any particular amounts. but may be applied .to machine havingonly the usual complement of number-keys. It may also be used for otherpurposes than the rriting of telephone bills and for btaining the totalsof items other than tax items.

The register is provided with an oscilla tory operating 1arin arrangedto cause an operation of the register each time it .is oscillated, andconnections are provided 1 between the and keys and the operating armtoefltect one oscillation of the operating arni when the 5 keyisoperated, and two oscillations of the operating arm when the 10 key isoperated.

It isan important point that the register ski,

is of the counter type, that is, of the type having a wheel of lowestdenominationaan ranged-to be advanced at every operation of theregister, and wheels of higher denomination arranged for operation onlyto carry overamounts run up on the wheel of-lowest denomination. Aregister of this type is -cheap to manufacture and easy to operate at atype stroke.

' Otherieatures and advantages will hereinafter appear.

In the accompanying drawings,

Figure .7 .is a side elevation rofone ofthe number-wheels of theregister or counter other thanthe units wheel.

The typewriting -machine comprises the usual number and alphabet; keys11, and, in -addition,--a special 5 key -5-.and'a special 10 key 10,preferably arranged at the rightehand end of the -keyboard,;a1l of.whichkeys .operatetypes 12 to printin-theusual manner. Abra-cket '13,-securedto the machine-frame 14, supports a register or counter-15 andconnections between the reg ister and stems .1 6 and 17 depending fromthe special-5 and 10 keys. These .con-

nections comprlse a rock-shaft 18, borne l in abusliing 19 carried bythelbr-acket 13, and rearwardly-extending cr-ankearm 20 on therock-shattlS. Headed studs Blatthe lower extremities .oiithe. stems 16and 17 .depending i'ronrthe 5. and 10 keys overlie and engage thecrank-arm .20 at distances from the 'centerof i the rock-shaft .18 which2 1,57 reoe are so related to each other that a full depression of the10 key rocks the shaft 18 through approximately twice the angle throughwhich it is rocked by a full depression of the 5 key.

At. its outer end the rock-shaft 18 has a second crank-arm 22, which isconnected to operate a gear-segment 23, pivoted. on the bracket 18, bymeans of a pin on the crank-arm 22 and a slot- 25 in the segn'ient. Thegearsegment meshes with and rotates a pinion 26 having a flange 27 uponwhich are mounted a pivoted pawl and a spring 29 for pressing the pawl.A hort sha 30 mounted on the bracket 13 terms the be ing for the pinion26 and also for a dish 3 having a single tooth The spring 29 presses thepawl 28 against the toothed disk 31 to effect a one-way driving:onnection therewith. A crank on the disk 31 is connected through a linkat to oscillate a register-operating arm 35, the arrangement be ing suchthat each full revolution the disk causes an oscillation of the arm Theparts are so proportioned and arranged that full depression of the 5 keyoscillates the arm 35 once and full depression of the 10 key oscillatesthe arm 35 twice. A spring 36, connected to the tail of the operatingarm 35 and to the bracket 13, maintains the oper ating arm normally atthe advance limit o its movement. A spring 37, connected to the gealsegment 23 and to the bracket 1-3, re

turns the gear-segment to its normal elevated position, and, through thepinion 26,

returns the pawl 28 independently of the toothed disk 31 and henceindependentl of the register-operating arm As has been stated, theregister 15 is of the type 01": the Veeder cyclon'ieter. but has itsunits wheel modified to adapt it to count by five. Theregister-operating arm is connected with and oscillates a yoke 38, uponwhich is pivotally mounted a series of pawls 39 spring-pressed towardnumberwheels 40 and 11 for cooperation with ratchet-teeth e2 thereon andwith intervening shallow and deep notches 43 and as in the usual way, toadvance the units wheel 4-0 one number space at each full operatingstroke of the yoke. Stops 4-", for preventing overthrow of the wheels 40and 41 and for locking them, are swung into and out of engagement withthe wheels by the yoke 38. Spring-pressed pawls l6 engage the wheels 10and 41 and prevent retrograde movement thereof. The units wheel l-Obears alternately the numerals O and 5, and has five deep notches 44arranged alternately with five shallow notches 43. By this arrangement acarry-over operation onto the tens wheel of the register is efi'ected atalternate operations of the register that is, each time that the unitswheel is advanced from 5 to O. The wheels 41 of higher denomination thanthe units wheel 40 are arranged with nine shallow notches and one deepnotch l ias usual, so that each tenth operation of one of them will beeti ective to cause a carryver operation onto the wheel of next higherdenomination. It will be apparent that one full oscillation of theregister-operating arm 35 will be cli'cctive to add tive to the totalexhibited by the register, and that two full oscillations o i theregisteroperatin arm will add live twice, increasing the total by ten.

The 5 key is shown .in its fullyalcpressed position in Figure 111 movingto this position, it moves the gear-segment 23 from the'position ofFigure 1, through the position of Figure 2, to that of Figure 5. Thesegment 23 turns the pinion 26 through one complete revolution in thismovement, and the crank through the pawl 28 and toothed disk 31, isturned in unison with the pinion, thus causing a complete oscillation ofthe register-operating arm to add iive to the total exhioited by theregister. As the 5 key rises, the spring 37 raises the gear-segment 23,causing the pinion 26 to he otated in the reverse direction. The pawl 28moves with the pinion 26 in this movement, but the toothed disk 31remains stationary, thereby permitting the crank 33 and theregister-operating arm to remain stationary also. The 10 key is arrangedto rock the shaft 18 twice as far as the 5 key rocks it. and hence todepress the gearsegment 23 sutliiciently to cause two completerevolutions of the pinion and therefore tvo full oscillations of theregister-oper ating arm 35, whereby ten w ll be added to the totalexhibited by the register.
